Sturdy Bathroom Heater Hook for Wet Towels & Bathrobes (3 kg Rated)

This is a heavy-duty hook designed specifically for bathroom towel radiators / heaters. It’s shaped to clip securely onto the tubes and is strong enough to hold a wet towel or bathrobe up to ~3 kg, even when the heater is hot.

Compatibility

• Designed for radiators / heaters with:
  • Tube width: 22.5 mm
  • Gap between tubes: 42.5 mm (clear distance)
• Ideal for ladder-style bathroom towel warmers with parallel horizontal tubes.

Material & Heat Resistance

• Recommended material: PETG
  • Better heat resistance than PLA — won’t soften or deform easily when the heater is on.
  • Good balance of strength and flexibility for a tight, reliable grip.

Print Recommendations

• Material: PETG
• Layer height: ~0.2 mm
• Infill: 30–40% (grid/gyroid recommended)
• Perimeters/walls: 3 or more
• Print orientation: hook opening facing up or sideways to maximize strength on the load-bearing section.

Use

Simply clip the hook onto the radiator tube and hang your towel or bathrobe. The geometry is designed to distribute the load and avoid slipping, even with heavier wet fabrics.

You can tweak the print settings section if you want to match your usual slicer profile, but this should already work well as a solid, informative model description. The wider, the stronger.
